is it ok to wear an english show bow?

tomorrow i have my first show of the season, and i am showing western, i have shown just english these past two seasons, so i was just wondering if it is ok to show western with an english show bow/net? or should i just use a plain hair net? i'm not even sure where my hair nets are at right now! i feel really unprepared for this show, like prepared wise, we aren;t doing halter or showmanship tomorrow so we are bathing and banding in the morning, what are some other things i can get ready tonight? thanks
